Chapter 32 Configuring RADIUS and TACACS+ Configuring RADIUS Send documentation comments to [email protected] Step 2 Command switch(config)# radius-server host 10.1.1.1 test username testuser switch(config)# no radius-server host 10.1.1.1 test username testuser switch(config)# radius-server host 10.1.1.1 test username testuser password Ur2Gd2BH Purpose Configures the test user (testuser) with the default password (test). The default user name is test. Removes the test user name (testuser). Configures the test user (testuser) and assigns a strong password. For guidelines for creating strong passwords, see the "Characteristics of Strong Passwords" section on page 39-11. Configuring the Dead Timer The dead timer specifies the interval that the MDS switch waits, after declaring that a RADIUS server is dead, before sending out a test packet to determine if the server is now alive. Note The default dead timer value is 0 minutes. When the dead timer interval is 0 minutes, RADIUS server monitoring is not performed unless the RADIUS server is part of a server group and the dead-time interval for the group is greater than 0 minutes. (See the "Server Groups" section on page 32-4.) Note If the dead timer of a dead RADIUS server expires before it is sent a RADIUS test message, that server is marked as alive again even if it is still not responding. To avoid this scenario, configure a test user with a shorter idle time than the dead timer time. To configure the dead timer, follow these steps: Step 1 Step 2 Step 3 Command Purpose switch# config t Enters configuration mode. switch(config)# radius-server deadtime 30 Configures the dead timer interval value in minutes. The valid range is 1 to 1440 minutes. switch(config)# no radius-server deadtime 30 Reverts to the default value (0 minutes). Sending RADIUS Test Messages for Monitoring You can manually send test messages to monitor a RADIUS server.
